CHARLES FOEHL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- I IALF TO HENRY RUHLAND, OF SAME PLACE.

CYLINDER-STOP FOR RE-VOLVERS.

SPECIFICATION forming part of Letters Patent No, 554,058, dated February 4, 1896.

Application filed July, 10, 1895.

[b all whom it may concern: 1

Be it known that I, CHARLESFQEHL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful linproveinent in Revolvers, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a revolver or firearm provided with novel-means forlocking the revolving cylinder of the same alternately while said chamber is at rest and just in advance of firing, as will be hereinafter set forth.

Figurel represents a partial side elevation and partial section of a revolver embodying my invention. Fig. 2 representsa section-of a portion; showing certainmembers in dlfien' ent positions from that shown in Fig. 1.

Similar letters of reference indicatecorresponding parts in the two figures.

Referring to the drawings, A designates the frame of a revolver or firearm below the rotary cylinder B, and O designates a springcatch, the rear end of which has the head D, which is adapted to enter the adjacent recess E in the outer peripheral wall of said cylinder, said head being also adapted to rest on the pin D on the upper end of the forward part of the trigger F, so as to be raised by the latter, the tendency of said catch being to lower when the trigger is pulled. The forward end of the catch has on its under side the notch or recess G, the wall of which is seated on the pin H, the latter being connected with the portion J of the frame A, the body of the spring bearing inpart upwardly against the frame A. In the trigger is a vertical recess K, which is occupied by the shank of a spring-pressed bolt or catch L, whose head is adapted to enter a portion of either of the recesses E in the cylinder B when the trigger is pulled, as will be hcrciuaftor more fully explained.

In the outer peripheral wall of the cylinder ii are rcdcssns- -N, which extend around the same at a right angle to the recesses E, so that when the catch .Ii rises and the cylinder 1-o iatcs the hcad of said catch enters the appreaching rcccss X, and is thus guided into the recess l5.

of, the front end of the trigger is formed with a small recess to receive said head.

The operation is as follows: When the trigger is in its normal position, the catch 0 is held elevated by the same, and its head D occupies a portion of the adjacent recess E, and thereby locks the cylinder and prevents rotation of the same. (See Fig. 1.) Now as the rear portion of the trigger is down or lowered, as most plainly shown in Fig. 1, the catch L is removed from the'recess E and remains. inoperative. When, however, the pistolor revolver is to be discharged and .the trigger drawn back, the pi n D lowers and the catch 0, previously bent upwardly, owing to its sprin'gy nature, also.

lowers, and causes itshead to withdraw from the recess Embers-by the cylinder is unlocked. The cylinder rotates as usual, and as the rear end of the trigger rises the catch L is raised and enters the adjacent recess N, which has advanced toward it, and is guided by the same to the adjacent recess E which it then occu-- pies, (see Fig. 2,) whereby the cylinder is locked by said catch L, this occurring just in advance of the firing or discharge, and continuing until the firing is accomplished. The trigger now returns to its first position, where; by the catch ,L lowers and the cylinder is unlocked, but as the pin D rises, due to the as-do cent of the front end of the trigger, the head of the catch 0 is forced into the recess E just above it, thus again locking the cylinder and preventing rotation of the same until the trigger is again pulled back, when the operations horeinbeforc described are repeated.

When the side plate of the revolver is removed, the catch 0 may be readily removed when broken, it being readily replaced by a.-

new piece, which may have the groove or-recuss G slipped over the pin II, thus restoring the catch in position.

llaviug thus described my invention, what I claim as new, and desire tosccuro by Letters Patent, .is

1. In a revolver, the cylinder provided with roccsscs around the same, the trigger having the catch l. therein, the frame formed withthe pin ll, and the catch 0 in said frame, said catches being adapted to alternately enter either of the recesses of tho cylinder, said too catch 0 having on its under side the recess G, I

whieh is seated 01 1 said pie H, substantially as described.

2; In a revolver, a cylinder having recesses around the same, and catches adapted to alternatel y enter said recesses, one of the catches being in the frame of the revolver, and the other catch being in the trigger, the catch in the frame having recesses in its heelend head ends on the under side thereof, and said frame and trigger hevin g pins thereon en whieh said to recesses are seated ubstantielly as described.
